SPECIFICATION forming part of Letters Patent No. 465,550, dated December 22, 1891.

Application led March 28, 1891. Serial No. 386,824. (No model.)

To ai?, whom t may concern:

Be it known that I, CARL ZANDER, manufacturer, of Vanzleben, in the 'Kingdom of Prussia and German Empire, have invented new and useful Improvements in Door-Closings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a seltlocking arrangement for two-winged doors and windows, and has for its object to effect a quick and sate closing of said doors or Windows.

In the annexed drawings,Figure l is a top view of a cupboard or press after taking oft' the top hoard and showing the press as closed. Fig. II shows the press open. Fig. III is a front view of the open press. Figs. IV, V, and VI are details.

Referring to the drawings, A is the front part of the press, having doors B and C. On the lower end ot` the narrow edge ofthe lefthand door B is a squeezer F, made ot soft metal or pressed leather, screwed onto the door in such manner that it can move and give way. A rounded pin or peg Eis screwed perpendicularly into the bottom board. The squeezer F ends in front in a round head, which, when the door is being closed, passes or puts itselt' behind the round peg E.

On the inner long side of the right-hand door C is a counterpresser or trigger G, which is screwed on so as to he opposite to the squeezer E, and in such manner that when the press is closed its front end presses against the head of the squeezer F, which by this action is forced behind peg E, and so holds the doors firmly in their closed position.

The new locking arrangement acts in the following manner: Then closing the press, rst shut the door B, which closing action causes the head ofthe squeezer F to pass or place itself loosely behind the round peg E.

(See Fig. I.) Then shut the right-hand door C. By closing the door C the counter-presser G is caused to press the head of the slack squeezer F firmly behind peg E. As Will he seen from Fig. I, the door B can not now be opened until the door C is opened.

This self-looking apparatus may with equal facility be applied to every kitchen-cupboard on which at presenta turn-button or common lock is iitted.

AS the common lock or turn -button is merely designed for connecting one Wing With the other, it is evident that for the purpose of locking it is not necessary that they should be used. All that isnecessary is siniply tc close both doors one after the other and the locking is complete. To open the cupboard, draw the right-hand Wing open, after Whichthe slack squeezer F ceases to act and the left wing can then be opened easily. The apparatus may in the same Way be applied for locking Windows and for other like purposes.

lVhat I claim, and desire to secure by Letters Patent of the United States, is-

In a closing device for doors, the combina tion, Witli the stationary peg or pin, of a flexible part secured to one door, having a locking portion adapted to pass by and loosely engage the rear face of said peg, and a rigid part secured to and projecting from the other door, adapted to engage said movable part and force the locking portion into rigid engagement with the peg, substantially as described.

In Witness whereof I have hereunto set my hand in presence of two Witnesses.
